Hmm - POSIX does say that strerror "shall map any value of type int to a
message", and not unsigned int, so it would seem better if cygwin didn't
convert to unsigned.  On the other hand, it is allowed to set errno to
EINVAL if errnum was not a valid error from <errno.h>, at which point
cygwin is in its right to print any message whatsoever (as long as it is a
message).  So it is debatable whether this is a regression or a conscious
design decision.
